There are small fish in the well, which I have seen in the article, but it is not as beautiful as goldfish. It is a delicious edible fish. I know there is a small jellyfish in the well, which also appears in the well of Hunan Province. It is called Peach Blossom Jellyfish, and its size is no more than one yuan. It is transparent and leisurely ups and downs in the water, which is really interesting. It is called peach blossom jellyfish because its body is as beautiful as peach blossom. More importantly, it appears in March and April of the peach blossom season every year, and disappears in other seasons. This jellyfish was sold and raised on the streets of Shanghai when I was a child. It was reported in the newspaper a year ago and has not disappeared yet.
